||Holux CF Card GPS
WAAS compatible, Great for use with many Pocket PCs to create a simple, low cost
soaring flight computer system. For details, see the PDA/GPS Systems
page. Works great with the optional GPA-18
External Antenna. The external antenna is not required in a
glider but is useful in a car.
The GR-271 CF GPS Receiver provides a host of features that make it easy
for integration and use. It uses 20 parallel satellite-tracking channels
for fast acquisition and reacquisition. It Support CF card type I
connector suitable PDA, Hand Held PC or PC device and using Star III/LP
low power consumption chipset.
